Threw a P0237 code on the way to work this morning, called Cummins here in Dallas and they had problems finding the P/N. They said it was P/N 4921497 saw in another post this was the P/N for 1998. 5 to 2000. Can anyone make sure this is the right number? Hate to drive that far in traffic with no power only to get wrong part. #@$%!
